-------------------------------------------------------------------------***----------------------------------------------------------------------Abstract In this study, a comprehensive examination of battery and supercapacitor-based hybrid energy storage systems (HESS) is conducted to enhance the performance of electric vehicles. By utilizing MATLAB Simulink as the primary analytical tool, we compare the efficiencies of fully active and passive hybrid energy storage systems. The primary objective is to integrate the power density of supercapacitors with the energy density of batteries, aiming to achieve superior performance metrics for electric cars. Our findings reveal that the fully active hybrid energy storage system demonstrates a more efficient power management capability, outperforming the passive system by generating over 41% more power under identical load conditions. This research not only underscores the potential of full-active HESS in electric vehicles but also sets a foundational base for future investigative endeavors in this rapidly evolving field.

1.INTRODUCTION The gasoline vehicles are an integral part of this world as they provide convenience and mobility to almost everyone. However, this convenience leads to pollution and an increase in greenhouse gas (GHG) emissions due to the combustion of gasoline. There have been many studies that indicate that the environment is negatively affected by gasoline vehicles as far as air contamination and release of greenhouse gases are concerned [1]. Carbon dioxide (CO2) emissions, mainly from fossil fuel combustion, have increased significantly since the beginning of the industrial revolution. CO2 is one of the gases contributing to greenhouse effects and, subsequently, climate change. Currently, transportation is responsible for over 20 % of worldwide CO₂ emissions resulting from the combustion of fossil fuels [2]. To reduce concentration levels of air pollutants like CO2 and other greenhouse gases, governments of quite a few developed countries have been promoting the use of electric vehicles (EVs) [3]. Energy storage systems (ESS) in electric vehicles (EVs) have an equivalent fuel consumption cost of $0.04 per mile compared to $0.10 per mile of internal combustion engine vehicles (ICEVs) [4].
